Recola: Recursive Computation of 1-Loop Amplitudes¶
Last updated: May 10, 2019
Recola is a Fortran95 computer program for the automated generation and numerical computation of tree and one-loop amplitudes at next-to-leading order (EW, QCD) in the Standard Model (SM) and Beyond the SM (BSM).
The following sections (see also the sidebar to the left) cover the installation and basic usage of the tools.
- Recola & Recola2
Currently two separately maintained versions exist:
- Recola is the original version (a.k.a Recola1) which is tailored for computations within the Standard Model in the ‘t Hooft–Feynman gauge.
- Recola2 is the successor of Recola, a generalized version for computations in BSM theories.
A list of releases and the release history can be found here.
- This section describes the building and installation steps of Recola and Recola2.
- This section describes the first steps in using Recola and Recola2 (requires the installation). We go through the example of using the demo files and setting up new demo files.
- Recola2 model files
- The Recola2 library requires new model files in a special format which we provide in this section. We describe the models and their configuration and compilations steps for a manual installation (not required when using the Recola2-Collier installation).
- API Docs
- We list all functions provided by the library accessible to the user. This section is still under construction.
Should you be using Recola for publication you are kindly asked to cite the relevant references.
